3 Claims. (Cl. 139-397) `This invention relates to improvements in pile fabrics,

.and more especially to velvets of the type which are double-woven, or are woven face-to-face by two separate shuttles, and in which the binding of two opposing, alternating groups of three pile threads each are woven in and spaced two picks apart. Every adjacent group of three pile threads is separated from the adjacent groups by one or two top and bottom warp threads, a ground warp thread on one side of each group of three pile warp threads being woven opposite to each individual pile warp thread when binding that particular ground warp thread.

-It is one of the objects of the present invention to obtain a better, more balanced and denser distribution of pile warp threads than has been heretofore obtained with a three-pick W type fast-locked pile warp thread tuft binding, and` -at the same time produce a smooth ICC Fig. 10 is a cross-sectional view, showing a composite of the pile threads illustrated in Figs. 6, 7 and 8;

Fig. 1l is a cross-sectional view, showing a composite of the pile threads illustrated in Figs. 2, 3, 4, 6, 7 and 8;

Fig. 12 is a diagrammatic view, showing the arrangement of the threads constituting the top and bottom ground fabrics and the pile threads which extend between them, and

Fig. 12a is a view showing the cross-sectional relation of the various threads to one another.

As is apparent from the diagrammatic view shown in Fig. 12, and in Figs. l and 5, the weft threads of one of the backings, herein referred to for convenience as the upper backings, are indicated respectively at 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 and 21. Similarly the weft threads in the second backing, or that herein referred to as the lower backing, are designated by the reference numerals 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 and 41. The warp threads in the upper backing includes the ground warp threads indicated at 50, 51, 52 and 53, while similar ground or backing warp threads 1 are provided in the lower backing at 54, 55, 56 and 57. The weave of the warp and weft threads in the upper velvet fabric having a thick, ribless pile cover which It is another object of the invention to provide a pile i fabric or velvet in Which less weft threads and less ground warp threads than heretofore required are needed to obtain the same thickness of pile cover. As `a result, the manufacturing cost of a fabric of this character is reduced tremendously and in some instances the production rate is increased to an extent of 70%.

It is still another object of the invention to provide a fabric in which there is a substantial reduction in the total weight of weft thread and ground thread materials, which in some cases amounts to as high as This weight reduction can be utilized or compensated for by the introduction of extra pile materials that help to produce a lustrous and more beautiful, non-rib producing cover on the fabric without making the total fabric weight too excessive.

It is still another object of the invention to provide a pile fabric or velvet having a dense, locked, fast pile cover of the character herein described and which helps materially in making this new type velvet crush-resistant. Since pile displacement and leaning pile are eliminated in this improved construction, the finishing operations are greatly simplified, and this in turn increases the likelihood of producing more first-grade quality pieces.

With these and other objects to be hereinafter set forth in View, I have devised the arrangement of parts to be hereinafter described and more particularly pointed out in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

Figs. l to 8 inclusive are respectively sections on the line 1-1, 22, 3 3, 4 4, 55, 6-6, 7-7 and 8-8 of Fig. l2;

Fig. 9 is a cross-sectional view, showing a composite of the three pile threads illustrated in Figs. 2, 3 and 4;

and lower ground fabrics is of plain weave formation., The paths of the various warp threads, including those Warp threads which form the pile for the two backings, are shown in Fig. 12 and in the diagrammatic cross-sectional views of Figs. 1 to 8 inclusive. The arrangement 4of threads shown in Figs. l to S inclusive constitutes one repeat in width and two repeats in length which is repeated throughout the fabric piece.

The warp pile thread 58 follows the path shown in Fig. 2, wherein it will be seen that by its alternation between the two sets of backing wefts, it forms the alternating W sections indicated at 60 and 61. rl`he path of the warp pile thread shown at 62 is seen in Fig. 3; the path of the warp pile thread shown at 64 is shown in Fig. 4. The three pile threads thus shown at 58, 62 and 64 constitute a set of pile threads arranged in staggered continuous interlocking relationship in respect to the ground weft threads. It is to be noted that each of the pile threads is locked in the ground fabrics by a fast W binding.

As shown, each of these adjacent groups of three pile warp threads each, as shown in Fig. 12, is separated by two ground warp threads indicated at 51, 52, 53 and 50 in the upper ground fabric, and at 55 and 56, 57 and 54 in the lower ground fabric. If only one top and bottom ground warp thread is used, then the top threads 51 and 53 as well as bottom ground threads 55 and 57 will be omitted.

Referring now to Figs. 6 to 8 inclusive wherein the second group of three pile warps is shown. In Fig. 6 is shown the path of the warp pile thread 65; Fig. 7 shows ythe path of the warp pile thread 66 and Fig. 8 shows the path of the warp pile thread 67.

When each of the three pile warp threads shown at 58, 62 and 64 in Figs. 2, 3 and 4 are consolidated into a complete cross section, as shown in Fig. 9, it will be noted that this series of W binders all interlock with one another, thus producing a resultant fast-locked V pile warp thread tuft binder over all of the upper backing fabric weft picks bearing reference numerals 11, 13, 15, 17, 19 and 2.1. Also, when each of the three Wall) pile threads shown at 65, 66 and 67 are consolidated into a complete cross section as shown in Fig. 10, it will be noted that the original series of three W binders all interlock with one another thus producing a resultant fast-locked V pile warp ,thread tuft binder evenly balanced over the weft picks numbered 10, 12, 14, 16, 18 and Z0. Fig. 11 is a consolidation of Figs. 9 and 10 and illustrates the density of the fast pile covering produced by the arrangement herein described.

-The distribution and placement of the described series of interlocking fast-locked W pile warp thread` binders as shown in Figs. 9 and 10, when woven with a tafeta ground as shown in Figs. .1 and 5, eliminates the undesirable rib effect commonly found iu the basic transparent velvet fabric weave.

In reference to Fig. 12 it is -to` be noted that this new type pile binding can Ialso be woven with half as many top ground or backing warp threads and half as many bottom ground or backing warp threads. That is to say, -threads 50 and 52 can be omitted in the top piece and threads 54 and 56 can be omitted in the bottom piece, thus further reducing production land material costs as well as resulting in a much improved pile distribution.

The weave herein described produces -a novel all-purpose type of velvet fabric that can be appropriately used for dress goods, millinery, collar material, ribbons and coating materials.

Having described `one embodiment of the invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all arrangements coming Within the scope of the Vannexed claims.
